HP Fortran Programmer Guide (766160-001, March 2014)

Table 4 Options for controlling optimization (continued)
FunctionOption
Provide [do not provide] feedback information about the
optimization process. This option is most useful at
optimization level 3 and higher. The default is +Onoinfo.
+O[no]info
Enable [disable] optimization, a predefined string that
indicates a category of optimizations (for example, those
+O[no]optimization
that do not increase code size) or a specific optimization
technology (for example, inlining). See the HP Fortran
Programmer’s Reference, for the different values for
optimization.
The other component of the back end is the code generator (CodeGen), which you can control by
using the command-line options in Table 1.5. These options allow you to specify (among other
things) that the output file include debugging or profiling information or that local variables be
saved in static memory.
Table 5 Options for controlling code generation
FunctionOption
Compile the named source files and leave [do not leave]
the assembly language output in corresponding files whose
names are suffixed with .s. The default is +noasm.
+[no]asm
Generate code for a specific version of the PA-RISC
architecture. model can be one of the following:
+DAmodel
• PA-RISC version number (1.1 or 2.0).
• A model number (for example, 750 or 870).
• One of the PA-RISC processor names (for example,
PA7000, PA7100, or PA8000).
• The word portable to generate code compatible
across all PA-RISC 1.1 and 2.0 workstations and
servers.

For information about using this option, see “Compiling
for different PA-RISC machines” (page 58).
Perform instruction scheduling appropriate for a specific
implementation of the PA-RISC architecture. model can be
one of the following:
+DSmodel
• PA-RISC version number (1.1 or 2.0).
• A model number (for example, 750 or 870).
• One of the PA-RISC processor names (for example,
PA7000, PA7100, or PA8000).
nl
For information about using this option, see “Compiling
for different PA-RISC machines” (page 58).
On Itanium processor family architecture, the defined values
for model are:
• blended: tune for best performance on a combination
of processors (i.e., Itanium or Itanium 2 processor). This
is the Itanium architecture default.
• itanium: tune for best performance on an Itanium
processor.
• itanium2: tune for best performance on an Itanium 2
processor.
• native: tune for best performance on the processor on
which the compiler is running.
